    Find maximum point of curve graph

    Hi,

    when finding maximum point of graph, where do I look at? The y axis or the x axis?
    Also, the answer should be "x=7" (for example), am I right?

    Thank you

    A point has always 2 coordinates if you're working in a plane, so a maximum M could be for example M(7,4).

    Hmm, but the question didn't state for the coordinates of maximum point of the curve, so I thought the answer would be different. Am I wrong?

    But for example x=7 can't represent a point, it represents a line (parallel to the y-axis).

    Yea, I will write the answer in coordinates then

    Thanks a lot

    Btw, how do I find the equation of line of symmetry if the line (line of symmetry) itself is in the y axis ? Which number do I take?

    Do you mean the y-axis itself? It's just x=0.
